AlphaCell BT

Broadband/Telecom VLRA Battery Series
  • Product Line: Batteries
AlphaCell BT
  • Front access terminal battery for Broadband/Telecom applications
  • Long life alloy design
  • Reduced headspace requirement provides higher energy density in cabinet or rack applications
  • Thermally welded case-to-cover bond to ensure a leak-proof seal
  • UL90 V-O flame retardant polypropylene case and cover
  • Certified non-spillable for transportation
  • Description

    The AlphaCell BT valve regulated lead acid battery features innovative front terminal design to maximize energy density with direct connect extrusion fusion weld technology. These models feature Absorbent Glass Mat (AGM) design for efficient gas recombination of up to 99% and flame-arresting, one-way pressure-relief vent for safety and long life. The AlphaCell BT also features threaded copper alloy inserts providing increased safety and reduced maintenance.
